Be it known-that we, HAROLD lVHrrnMAN WOODALL, residing at Royston, \Vimborne,

tion. i

and ARTHUR MoDoUeALL DUCKHAM, residing in' Walden, Alexandra Road, Upper Parkstone, in the county of Dorset, England, civil engineers, subjects of the King of Great Britain, have invent-ed certain new and useful Im rovementsRelating to Vertical Retorts Coal, of which the following is a specifica- The present invention relates to vertical retorts adapted to receive coal for the carbonizat-ion or distillation thereof by means of heat applied to the exterior of such retorts, the same being of the type disclosed in our English Patent No. 11,956 of 1905. In this patent we describe a vertical retort having longitudinal ribs projecting from its outer surface and of such depth that they abut against the setting or against corresponding ribs of adjacent retorts. I

In our present nvention the retort sectlons or some of them are made with a flan e at each end and with shallow ribs ex- .inlike reference characters designate the. 35'

same parts in the several views and in which,

Figure 1 is'a partial vertical section through a retort setting constructed according tothe invention; Fig. 2 a partial horizontal section thereof, and Fig; 8 an elevation showing a single retort section apart from its setting. w The retort sections a are made with top and bottom flanges b, a, and with longitudinal ribs (l. These sections are set in brickwork columns 6 extending from the sides of the setting 1 and others built between the retorts. v

The bricks-on that side of each column which is adjacent to the retort have rounded corners, and are grooved to receiveone of the ribs on the retort. In this manner the retorts are held securely and the area of the retort protected from the heat by the supporting column is reduced to a minimum.

In order that the flues may; be suitably or the Destructive Distillation of contracted in cross-section so as to hold the heated currents in contact with the retorts more closely, the sides of the setting f are shaped to surround each retort as far as pos sible as clearly shown in Fig. 2, at f.

Having thus fully described our invention What we claim as new and desire to secure by Letters Patent is as follows 1. An apparatus of the class described comprising vertical retorts provided with longitudinal ribs, a setting arranged to in close said retorts and columns disposed between said retorts and arranged to engage the ribs on the retort sections.

2. An apparatus of the class described comprising vertical retort sections provided with longitudinal ribs, a setting arranged to inclose said retort sections, and brick work columns disposed between said retorts and intermediate said retorts and the setting, said columns having rounded inner corners arranged to engage said ribs on the retort sections.

3. An apparatus of the class described comprising a vertical retort. composed of superposed sections, each section having externally flanged ends and longitudinal ribs connecting said flanged ends.

i. A retort section comprising, a hollow body having externally flanged ends and longitudinal ribs connecting said flanged -ends.

5. An apparatus of the class described comprising vertical retorts composed of sections having flanged ends and longitudinal ribs, a setting therefor arranged to encompass each retort section to a maximum extent and 'brick work columns disposed between said retorts and intermediate said rerounded inner corners and arranged to engage said ribs on the retort sections.

In testimony whereof we aflix our signatures in the presence of two witnesses.
